Acid-free primer Ultrabond Ultrabond is a primer whose formula does not contain methacrylic acid. The product is safe for the health of the nail plate and the area around the nail, it does not have a sharp smell, unlike products that contain acid. The acid-free nail primer has a liquid consistency, which is convenient to pick up with a brush and apply a thin layer to the surface of the nail. The texture allows you to cover the entire nail plate in one movement. The created layer extends the wear of the coating and protects the natural nail from the influence of polymer dyes. Acid-free nail extension primers prevent yellowness and delamination of the nail plate. They also disinfect the nail so that microorganisms do not develop between the coating and the natural surface.
